Product Description:

The DDS02.1-W050-RS01-03-FW drive is manufactured by Bosch Rexroth Indramat and belongs to the DDS Drive Controllers series. It is intended to regulate torque, speed, and position in multi-axis industrial automation systems that use synchronous or induction servomotors. By converting control commands into three-phase output, the unit forms the link between a higher-level motion controller and the mechanical load. This arrangement supports coordinated movement on packaging lines, material-handling equipment, and machine tools. It is suitable for applications where several axes must accelerate, decelerate, and hold position with repeatable response.

Communication with the motion controller is handled over the SERCOS interface, allowing deterministic cyclic data exchange and rapid parameter access. Thermal management relies on air from inside the control cabinet, so cabinet airflow removes heat without external ducting. The power section delivers a continuous output of 50 A, giving matched motors enough current for dynamic acceleration and steady operation. Rotor position is returned by resolver feedback, which provides analog sine-cosine signals that remain accurate under electrical noise and across the operating speed range. The module combines current regulation, velocity loops, and protective monitoring in one unit rather than relying on separate analog boards.

The drive uses firmware ordered as a separate subitem, so the software package can be matched to the required function set. The unit carries Function ID 01, belongs to Line 02, and is Version 1. These identifiers help keep the drive aligned with compatible parameter files and SERCOS telegram structures when it is installed in existing Rexroth automation racks. Using the correct software and hardware combination helps maintain predictable communication behavior and axis control within a shared multi-axis system. This is particularly useful when the drive is added to a rack that already uses established SERCOS timing and parameter conventions.
